Journal Article 1993

Autor: Shapiro, Barry I. Sanders, J.H. Reddy, K.C. Baker, T.G.

This study modeled the introduction of new early cultivars of millet and cowpea, higher cowpea densities, and various fertilization strategies. Model results were then compared with farmer behaviour before and after the availability of these new technologies. The model correctly identified the tw...

Double-cropping of soybeans and wheat is often promoted by extension personnel. This paper seeks to explain how the decision to adopt double-cropping is made, using a Tobit regression model. Tobit makes use of more of the information in the data set than do logit or probit and explains not only t...

In semiarid West Africa, inorganic fertilizer use and sustainability objectives are complementary. With increasing population pressure and low levels of purchased inputs, crop yields in many regions are declining. Moderate use of inorganic fertilizer is required for increasing yields in a sustain...

This paper addresses the problem - with increasing values of land, crops and livestock in the semi-arid region, what happens to the livestock component? The conventional wisdom is that abundant land in more remote areas is more conductive to livestock Development than where human population densi...

An important debate is currently under way among researchers and policy makers about the relative merits of using organic versus inorganic fertilisers to improve soil fertility in semi-arid areas of sub-Saharan Africa. Environmentalists argue that use of inorganic fertiliser contributes to natura...
